AXLE-REPAIRING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 603,636, dated May 10, 1898.

Application filed September 18, 1897. Serial No. 652,154. (No model.)

To cir/ZZ whom, it may concern:

Be it known that I, WILLIE ALICE HAMMER, a citizen of the United States, residing at Fairlie, in the county of I-Iunt and State of Texas, have invented a new and useful Axle-Repairing Apparatus, of which the following is a particularly pointed out in the appended claims.

In the drawings, Figure l is a perspective View of an apparatus constructed in `accord'- ance withpmy invention applied in the operative position to a vehicle, the latter being in position for the introduction of the metal iilling. Fig. 2 is a central sectional view of one of the bearings. Fig. 3 is a detail view in perspective of the wheel-clamp. Fig. 4. is a similar view of the spindle-support in its folded position. Fig. 5 is a similar view of the plumb for insuring the vertical position of the spindles.

Similar numerals of reference indicate corresponding parts in all the iigures of the drawings. v

In proceeding to repair worn vehicle-bearings it is my object'to so arrange and support the parts of a vehicle that Babbitt or equiv- -alent metal may be poured into the inner ends of the wheel-boxes to fill the interval .between the inner surfaces of said boxes and .the surfaces of the spindles. In order to accomplish this object, I employ a spindle-support l, consisting of a bar which is adapted Vto rest upon a horizontal surface, as the ground or iioor, and is provided contiguous to its extremities with spindle-seats 2 and 3,

one of which is adjustable longitudinally of the bar, and preferably has its stem fitted in a longitudinal slot 4 in the bar. In the construction illustratedthe stems of the spindleseats are extended through the bar 1 and also through pivotal sills 5, adapted to be arranged transversely with relation to the bar and held in place by nuts 6, threaded upon the lower extremities of the stems of said spindle-seats. In order to facilitate the folding of this supporting-bar when not in use, said sills are adapted to swing to a position parallel with the bar,.and to further facilitate folding the bar it is jointed at an inter- 'mediate point to form sections connected by a hinge 7.

In practice the vehicle of which the bearings are to beV repaired is arranged with the extremities of its axle-spindles upon one side in said seats, the vehicle being turned upon its side, whereby the axlesocoupy vertical positions; but in order to preventthe sills from turning or becoming displaced during the introduction of the molten metal I provide aiwheel-clamp 8, consisting of twin parallel bars 8a 8b, secured together at intervals by bolts 9 and adapted to be arranged, respectively, upon oppositeK-sides of the front and rear wheels upon one. side of the vehicle and to be held in tight frictional contact therewith by the tightening of said bolts. Obviously this operation of clamping the wheels must be accomplished prior to turning the vehicle upon its side, and in order to facilitate the folding of the clamp each member th ereof is preferably of sectional construction, with the members connected by hinges 10.

After the vehicle has .been turned to said position it is necessary to accurately plumb theaxles in order that the molten metal when introduced into the wheel-boxes may flow uniformly around the spindles, and to accomplish this I employ a .plumb 1l, consisting of a flexibly-suspended weight, connected with spring provides for the separation of the front and rear arms to properly engage axles of different thicknesses;

When by means of the plumb the axles have been arranged in a truly vertical position, the

IOO

molten metal may be introduced at the inner ends of the wheel-.boxes and allowed to entirely iill the interval between the surfaces of said box and spindle, whereupon, after cooling, the spindle is provided with a sheath or sleeve 16, constituting a new spindle-surface; but in order to prevent this sleeve from turn-V ing upon the spindle the latter, prior to the operation, should be thoroughly cleaned and provided with one or more grooves or depressions 17, whereby when the molten metal has `flowed into the axle-box it will also fill said depressions and thereby form ykeys 18.

ing the axle-seats on the base to correspond with the interval between the axles the vehicle is canted to dispose the extremities of the axle-spindles in the cups of the seats, whereupon the bearing of the outer ends of the hub-sleeves or the shoulders usually provided at the outer ends of the hubs upon the axle-nuts will dispose the wheels respectively in planes perpendicular to the axles; but in order that there may be no tendency .upon 'the part of the wheels to occupy positions at an angle to the axle and also in order to insure the uniform iowing of the molten metal around the spindles it is desirable to plumb the axles with the means provided for that purpose or other means analogous thereto. After having attained the desired vertical position of the axles they may be so held,

manually, during the pouring operation, or` .they may be fastened by any suitable ap-` (N ot shown, and consequently no part .of my present invention.) The specificform :illustrated in the drawings is desirable by reason .of the Afacility with which it can, be applied to the axles and also by reason of paratus.

the simplicity of its construction, the same being applicable to axles of various constructions and sizes without affecting its efficiency in the capacity of indicating a vertical position of the axles. It is obvious that the wheel-clamp, in addition to preventing rotary movement of the wheels during the repairing operation, prevents the swinging of .the front or steering axle of the vehicle, and hence maintains the parts rmly in the proper position for seating the axle extremi- 'ties in the cups.

Furthermore, I have found in practice that it is vdesirable in order to facilitate the removal of the wheels after the operation, as above indicated, to fit in the inner end `of each hub a forming-strip 19, of pasteboard or .equivalent material, of cross-sectionally,

tapered or wedge-shaped construction. The exterior surface of this forming-strip accurately ts the inner surface of the hub, while the inner surface thereof is beveled to produce a beveled shoulder on the sleeve formed by the Babbitt metal, and this beveled surface has the lfurther effect of causing oil,

which works inwardly upon the axle-spindle, to flow back upon the spindle to avoid waste also, the abrupt inner surface of the enlarge# ment or collar 20, constructed within the Vforrning-strip, constitutes a dustguard to prevent sand and vother foreign substances from gaining access to the surface of the spindle.

It frequently happens that the axle-box has become interiorly scored or grooved by sand or foreign substances which have worked into the same, and in order to prevent the molten metal from gaining access to these grooves and thus forming keys to prevent the wheel from turning upon the spindle I have found it necessary in certain cases to cover such After adjusting the wheel-clamp and spacdepressions, as by means of paper, temporarily fastened by an adhesive material to the inner surface of the axle-box.

Various changes in the form, proportion, and the minor details of construction may be resorted .to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my invention, what I claim is`- 1. An axle-repairing apparatus, having. a supporting-bar provided with spaced caps for supporting the extremities of the front and rear axle-spindles, in combination with means for securing the wheels which are mounted upon said spindles from accidental displacement, substantially as specified.

2. An axle-repairing apparatus, having a supporting-bar provided with vspaced spindleseats for supporting the extremities of front and rear axle-spindles, one of said seats being adjustable longitudinally of the bar, and means for securing the adjustable seat at the desired adjustment, in combination with means for clamping the wheels which are m ounted upon said front and rear axle-spindles, to prevent accidental displacement, substantially as specified. l

3. An axle-repairing apparatus, having a supporting-bar provided with seats to receive the extremities of the front and rear axlespindles, one of which is adjustable longitudinally of the bar, means for securing the adjustable spindle-seat at the desired adjustment, and pivotal sills mounted upon the bar for lateral extension to prevent displacement thereof, substantially as speciiied.

4. An axle-repairing apparatus, having a supporting-bar provided with spaced seats to receive the extremities of front and rear axle-spindles, and pivotal sills fulcrumed in the transverse planes of said seats and adapted to be extended laterally to project beyond the side edges of the supporting-bar, said bar being yof sectional construction and having its members hingedly connected for folding, substantially as specified.

5. An axle-repairing apparatus having a wheel-clamp provided with means for simultaneouslyengaging front and rear vehiclewheels to prevent rotary movement thereof upon their spindles and also prevent pivotal movement of the front-Wheel axle, in combination with means for seating the axles of the IOO IIO

Wheels When in an upright position, substantially as specied.

6. An axle-repairing apparatus having a Wheel-clamp comprising sectional coperating clamp-bars, the members of which are hingedly connected for folding in opposite means for attaching said plumb to an axle, substantially as specified.

' 8. In an apparatus of the class described, the combination with axle-supporting and Wheel-clamping devices, of a plumb having a clip provided with front and rear arms con-l neeted by an expansion coiled spring and adapted to bear respectively upon opposite side surfaces of a Wheel-axle, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
